I can confirm that the download link seems to not be functioning at the moment. The only other link to R3 that I have does not work either. I recommend trying again later today and letting us know here if it still is not working. Good luck!

We’re sorry to hear that the link to download the Intel RealSense SDK R3 was not working. We have tried to download it and it is working, we would like to know if you have tried again and if it is working for you.
It's back and working now.
Great thanks for your head-up.
Great news Justin. Good luck! Please come to the forum again if you have any problems.
